    摘要: A dual hoist crane is provided with a heave compensation system that can be used for both the main and for the auxiliary hoisting assembly. The heave compensation system includes a first set of sheaves for guiding the main hoisting cable and a second set of sheaves for guiding the auxiliary hoisting cable. The heave compensation system is configured to individually lock the first set of sheaves and the second set of sheaves to a heave compensation cylinder, for respectively providing the main hoisting assembly and the auxiliary hoisting assembly with heave compensation.

    摘要: Providing energy to an energy consuming piece of equipment and/or tool during offshore operations. Use is made of a crane including a substructure, a boom mounted on the substructure, one or more hoist winches and cables, as well as an object suspension device suspended from the boom by the cables. A piece of equipment or tool is suspended from the object suspension device. An energy storage unit is provided on the object suspension device and has an input connector. The boom may be provided with an output connector of an energy charging unit and in a lower supply position of the object suspension device it is disconnected from the input connector of the energy storage unit. The piece of equipment or tool is then run on energy supplied by the energy storage unit. Moving the object suspension device to a charging position thereof by employing the hoist assembly of the crane brings the input connector of the energy storage unit in close proximity of the output connector of the energy charging unit which are then interconnected to charge the energy storage unit from a separate energy source.

    摘要: The invention relates to a mobile crane having a telescopic boom that is luffably coupled to a superstructure and that comprises a coupling section and at least one telescopic section supported therein in a retractable and extendable manner. At least one guying support is fastened to the coupling section and is connected to the coupling section or to the superstructure via a first guying and to a connection piece at a telescopic section via a second guying. In accordance with the invention, the second guying comprises at least two guying elements coupled with one another. The second guying is thereby adjustable in length and is thus adaptable to the extension length of the telescopic boom such that at least one of the mutually coupled guying elements is directly releasably connectable to the guying support. The invention further relates to a guying system for a mobile crane in accordance with the invention, to a method of moving a mobile crane in accordance with the invention into a guyed work position, and to a method of varying the extension length of the guyed telescopic boom of a mobile crane in accordance with the invention.

    摘要: A mobile crane comprising a telescopic boom which has a main casing with linearly moveable inner casings. Guying equipment can be added to the telescopic boom, where at least one securing region arranged on the main casing is provided for the fixing of the guying equipment. In order for the adding and removal of the guying equipment to and from from mobile crane to be carried out more easily and safely, at least one coupling region is arranged on one of the inner casings for adding and/or removing the guying equipment and which can be connected to the same. In this way, the guying equipment can be received directly from a transport unit by the at least partially extended telescopic boom, the guying equipment can be moved onto the main casing by retracting the telescopic boom and coupled to the same.

    摘要: Provided is a crane including a guy link coupling part easily accommodatable at a predetermined position thereof. The guy link coupling part has a pair of left and right link members each extending in a front-rear direction, and a coupling member extending in a left-right direction and connecting the pair of link members to each other. A linking and retaining structure includes a first retainer provided on a boom for retaining the coupling member to restrict the coupling member from moving in the front-rear direction. The first retainer has: a first slope surface slanting inward of the boom, from a proximal position of the boom toward a distal end thereof; a second slope surface located closer to the distal end of the boom than the first slope surface and slanting outward of the boom; and a recess part disposed between the first slope surface and the second slope surface.

    摘要: A vehicle crane system includes a vehicle crane with an attachment part, in particular a bracing device, which can be mounted on and removed from the telescopic jib of the vehicle crane, and to an attachment part transporting unit for transporting an attachment part of a telescopic jib of the vehicle crane. A mobile transporting device is provided for transporting the attachment part and has at least one loading arm, the free supporting end of which can be coupled to the attachment part carried or to be carried on the transporting device. The loading arm is arranged movably on the transporting device such that the attachment part can be moved between the transporting device and the telescopic jib. Furthermore, the transporting device has a tilting device which is designed for raising and lowering one side of the attachment part carried or to be carried on the transporting device.
